Bharti Bains, Rohit Vaid . Selective Forwarding based Intrusion Detection System for Secure Wireless Sensor Network. International Journal of Computer Applications. 77, 13 ( September 2013), 20-26. DOI=10.5120/13544-1328
Security is the major threat in wireless sensor network. Deployment of sensor nodes in hostile environment makes vulnerable to a variety of potential attacks like Hello flood attack, wormhole attack, black hole attack and selective forward attack. In a black hole attack, compromised node drops all the packets forwarding through it. A special case of black hole attack is selective forwarding attack, where compromised node drops packets selectively, which may deteriorate the network efficiency. Selective forwarding attack is hard to detect, since packet drops in sensor networks may be caused by unreliable wireless communications or node failures. The proposed work is based on centralized intrusion detection scheme which uses multi level dynamic tree routing. It can detect both black hole attack and selective forwarding attack. The proposed scheme is compared with existing scheme and found that the packet delivery ratio in the proposed scheme is much more than the existing scheme.
